Abstract
Intracranial pial Arteriovenous Fistulas (AVFs) are rare cerebral vascular lesions composed of one or more arterial connections to a single venous channel. We report a 50-year-old patient with a ruptured pial AVF located in an eloquent area. Microsurgery for pial AVF occlusion was proposed with awake craniotomy for motor function and neurological evaluation. Awake craniotomy is a technique that is especially useful for cerebral vascular lesions in eloquent areas, where an occlusion often compromises or suppresses the blood supply, culminating in ischemia with consequent transient or definitive deficits in neurological function.
